Definitions

  • An aspect of the present invention generally relates to a toilet seat.
  • the toilet seat is configured, for example, by joining an upper plate with which the buttocks contact and a bottom plate provided on the toilet side.
  • Patent Document 1 discloses a technique for joining these resin parts by filling a passage formed between resin parts with a joining resin.
  • Toilet seats are required to suppress the occurrence of seams, steps, gaps, and the like at the joint between the top plate and the bottom plate in order to improve cleanability.
  • the manufacturing method of filling the resin it is possible to relatively easily manufacture a toilet seat having a high cleaning property by reducing the number of post-processes such as grinding and polishing as compared with other manufacturing methods.

  • the contact area between the second drooping portion and the mold can be made smaller, and the contact pressure between the lower end portion of the second drooping portion and the mold, which becomes a part of the injection port, can be further increased. Thereby, resin leak can be suppressed more reliably.
